6 Claims.

This invention relates generally to range burners and in particular is directed to an improvement in range burner mountings. In present ranges, the `burners are mounted beneath the grille in a stationary position relative thereto. With such arrangement when the fuel control valve is fully open, the distance between the burner and grille is such that the hottest point of the flame is in proper relation to the bottom of a vessel on the grille; however, when the valve is partially closed `to reduce the llame length, the hottest point of the ame is too far removed from the vessel bottom for-highest e-fciency.

To overcome `this objection, it is our principal object to provide a range burner mounting wherein the burner is mounted for movement towards or away from the grille; such mounting including manual actuating mechanism. to effect such burner movement. By reason of such assembly, the burner can be raised toward the grille when the flame is reduced in length, and lowered away from the grille when the flame is at maximum length.

As an additional object, we arrange the burner actuating mechanism in operative connection with the fuel control valve stem whereby upon rotation of said stem to a predetermined valve position, the burner will be automatically adjusted to proper relative position beneath the grille for the flame length at such valve position.

A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective for the purpose for which it is designed.

These objects we accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

In the drawing similar characters of reference indicate corresponding parts in the several views:

Figure 1 is a side elevation partly in section, of our improved range burner mounting as installed and with the burner in lowered position.

Figure 2 is a similar view but with the burner in raised position.

Figure 3 is a sectional plan on line 3--3 of Fig. 2.

Referring now more particularly to the characters of reference on the drawing, the numeral I indicates the top of a range provided with a removable grille 2; a front plate or skirt 3 eX- tending vertically downward from the front edge of the top-all as usual.

A burner 4, having a vertical depending neck 5, is disposed beneath the grille. A relatively wide collar 5, formed with an outwardly projecting top flange 1, surrounds the neck 5. Pins disposed at i relative to each other, are threaded into bosses 9 and project radially from the neck into opposed spiral slots Ill in the collar 5. The collar 6 is rotatably mountedin position by means of an annular supporting member II which engages beneath flange 1 and is provided with lugs I2 which are bolted to a horizontal bar I3 at spaced points as clearly shown in Fig. 3, The burner is provided with an integral and depending fork I4 which slidably straddles bar I3 l and prevents rotation of the burner.

A fuel and air mixing pipe I5, of goose-neck configuration, rests intermediate its ends on another horizontal bar I6. The inner end of pipe I5 is vertical, as at I1, and slidably but closely engages within burner neck 5.

The outer end of the pipe is formed with the usual air intake bell I8 into which a fuel jet I9 extends from a valve 20 interposed in a horizontal fuel supply pipe 2| disposed adjacent skirt 3.

A valve stem 22 extends forward horizontally from the valve 20 through the skirt 3, a radial handle 23 being'flxed on the outer end of the stem. A bevel gear 24 is xed on stem 22 close behind skirt 3 and meshes with another bevel gear 25 mounted horizontally below stem 22 as shown. A radial arm 26 is fixed on gear 25 and a pivoted connecting rod 21 extends from the outer end of arm 26 to the lower edge of collar 6. The amount of throw of rod 21 may be adjusted by changing the point of pivotal connection with arm 26.

Operation In use our device functions in the following manner: When the handle 23 is turned so that the valve is fully open and the burner flame at full length, gear actuated arm 26 and rod 21 will have rotated collar 6 in such direction that pins 8 have moved to the lower end of slots I0 lowering the burner.

However, when the valve 20 is partially closed, the collar will be turned a certain amount in the other direction causing pins 8 to slide up the slots and raise the burner an amount proportionate to the reduction in flame length.

As a result the hottest point of the ame can be maintained in proper position relative to the bottom of a vessel on the grille.

Our improved burner mounting is Very eilcient and effects substantial savingsin fuel, and when the flame is reduced in length, the heating ability and heating speed of the llame is materially increased over present day stationary burners due to the fact that the shorter flame is brought into close proximity to the bottom of a vessel on the grille.

From the foregoing description it Will be readily seen that We have produced such a device as substantially fulfills the objects of the invention as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention as defined by the appended claims.

Having thus described our invention, what We claim as new and useful and desire to secure by Letters Patent is:

1. In a gas range, a grille, a burner disposed beneath the grille, said burner having a vertical neck, a collar surrounding the neck, means mounting the burner and collar for relative rotation, means between the neck and collar to effect vertical movement of the burner upon such relative rotation, a fuel control valve having a stem, and means connected to the stem to rotate the neck and collar relative to each other upon rotation of said stem.

2. In a gas range, a grille, a burner disposed beneath the grille, said burner having a vertical neck, means mounting the neck for vertical movement but against rotation, a member mounted for rotation about said neck and having a spiral slot therein, a radial pin on the neck projectinginto said slot, and manually actuated means to rotate said member and move the burner vertically.

3. A range as in claim 2 including a fuel control valve having a stem, said last named means including a lever assembly connected between said stern and the rotatable member.

4. In a gas range, a grille, a burner disposed beneath the grille, said burner having a vertical neck, means mounting the burner for vertical movement but against rotation, a collar surrounding the neck and rotatable relative thereto, the collar having a spiral slot therein, a radial pin mounted on the neck and engaging in the slot, an air and fuel mixing pipe having a vertical inner end slidably engaging in the burner neck, a fuel control valve associated with the outer end of said pipe, the valve having a rotatable stem, and means connected between the stem and collar whereby to rotate the latter upon rotation of the stem.

5. A range as in claim 4 in which said first named means comprises a vertical fork formed on the burner and a xed bar over which said fork slidably engages.

6, A range as in claim 4 in which said last named means includes a rod connected at one end to the collar at a point radially of its axis, an arm pivoted for rotation in the same plane as the rod and mounted for actuation from said stem, the other end of the rod being connected to the arm.
